<SCRIPT type=text/javascript>

var t = n = 0, count = $("#focus_list a").size();

$(function(){ 

 $("#focus_list a:not(:first-child)").hide();

 $("#focus_content div:not(:first-child)").hide();

 $("#focus_text li").click(function() {

  var i = $(this).text() - 1;

  n = i;

  if (i >= count) return;

  //$("#focus_info").html($("#focus_list a").eq(i).find("img").attr(\'alt\'));

  $("#focus_info").unbind().click(function(){window.open($("#focus_list a").eq(i).attr(\'href\'), "_blank")})

  $("#focus_list a").filter(":visible").fadeOut(1).parent().children().eq(i).fadeIn(1);

 });

 t = setInterval("showAuto()", 3000);

})

function showAuto()
